Re: [PHP] Associative array issues with loading values after initialization
funny how that perl code looks so much like php ... or is it the other way
around.

okay, so all the while, next, key stuff is gonna make your eyes bleed.
we have foreach() ... it is your friend:
function dropBox($items, $selected, $name, $output = false)
{
if (!is_array($items))
return;
$opts = array();
foreach($items as $k = $v) {
$k = htmlentities($k, ENT_QUOTES); // htmlentities should really
$v = htmlentities($v, ENT_QUOTES); // be getting a charset are 4rd arg
$s = $k == $selected ? ' selected=selected' : '';
$opts[] = 'option value='.$k.''.$s.''.$v.'/option';
}
$html = 'select name='.$name.''.join('', $opts).'/select';
if ($output)
echo $html;
else
return $html;
}

I know how to write this in perl but for some reason, when I write it
in PHP it doesn't work.
In perl it would be (roughly):
function crm_get_country_list(){
global $dbh;
$result = mysql_query(SELECT * FROM countries ORDER BY
pk_country_id ASC, $dbh) or die(mysql_error());
my %country_list;
while ($row = mysql_fetch_assoc($result)){
$country_list[$row['pk_countryID']] = $row['country_name'];
}
return \%country_list;
}
What am I doing wrong here?
you learnt perl first :-D
Thanks in advance,
Tom

I'd use foreach() here and avoid next(). At least, reset the array
first. And maybe pass the array by reference:
function dropbox_from_list($list, $selected_index)
{
foreach($list as $k = $v)
{
$k = key($nex);
if (strcmp($selected_index, $k) == 0) {
$select = ' SELECTED';

else {
$select = '';
}
print(option value='.$k.'.$select..$nex[$k]./option);
}
}
Maybe you should also add what it is that's not working.

Are you starting with an empty key value so that you'll have an
empty option in your select list? Why not just print an empty one?
while ($row = mysql_fetch_assoc($result)){
$country_list[$row['pk_countryID']] = $row['country_name'];
}
return $country_list;
}
Start with the obvious: what does $country_list contain when it's
returned?
Again, some details about what you're getting would go a long way
toward getting some advice.
You should think about changing that SELECTED line to $select = '
selected=selected'; as the previous way is not recommended for modern
code.

Re: [PHP] Associative array issues with loading values after initialization
This came straight out of the docs and it doesn't even work. It throws
PHP Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING on
the line 'one' = 1,
What is wrong with how I am trying to do this loop??
Thanks,
Tom
$a = array(
'one' = 1,
'two' = 2,
'three' = 3,
'seventeen' = 17
);
foreach ($a as $k = $v) {
echo \$a[$k] = $v.\n;
}

Re: [PHP] Associative array issues with loading values after initialization
I found the issue. The whitespace in between $list as $k = $V was all
not truly whitespace. Gotta love BBEdit...
